Chapter 13: Q.13.32 (page 542)

Suppose that a one-way ANOVA is being performed to compare the means of three populations and that the sample sizes are 10, 12, and 15. Determine the degrees of freedom for the F-statistic.

Short Answer

Expert verified

F- statistic has role="math" localid="1652237094308" (2,34) degrees of freedom.

Step by step solution

01

Given Information

Population densityk=3.

The sample sizes are 10,12,15.

02

Explanation

The number of observations total:

n=10+12+15

=37

The F-statistic has degrees of freedom of

df=(k-1,n-k)

=(3-1,37-3)

=(2,34)

Staph Infections. In the article "Using EDE, ANOVA and Regression to Optimize Some Microbiology Data" (Journal of Statistics Education, Vol. 12, No. 2, online), N. Binnie analyzed bacteria culture data collected by G. Cooper at the Auckland University of Technology. Five strains of cultured Staphylococcus aureus bacteria that cause staph infections were observed for 24hours at 27oC. The following table reports bacteria counts, in millions, for different cases from each of the five strains.

At the 5%significance level, do the data provide sufficient evidence to conclude that a difference exists in mean bacteria counts among the five strains of Staphylococcus aureus? (Note: T1=104,T2=129, T3=185,T4=98,T5=194,危x2i=25,424.)

For an \(F\)-curve with \(df=(20,21), find

a. \(F_{0.01}\)

b. \(F_{0.05}\)

c. \(F_{0.10}\)

Smoking and Cotinine. Smoking during pregnancy is hazardous to both the mother and baby, Passive smoking, or inhalation of second-hand smoke, is also a concern. In the article "detection of Cotinine in Neonate Meconium as a Marker for Nicotine Exposure in Utero" (Eastern Mediterranean Health Journal, Vol. 10no. 12, Pp .96-105), N. Sherif et al. studied whether active smoking or passive-smoking mothers were passing along harmful chemicals to their babies. The level of cotinine in a newborn's first meconium, which is the infant's stool, is reported on the WeissStats site for independent samples of active-, passive-, and non-smoking mothers. Cotinine levels are measured in nanograms per millilitre (ng/mL). Use the technology of your choice to decide whether presuming that the assumptions of normal populations and equal population standard deviations are met is reasonable.

Explain the reason for the word variance in the phrase analysis of variance.
